Description

A kind of ultra-thin tube and its processing method
Technical field
The present invention relates to tubing manufacturing technology, especially a kind of ultra-thin tube and its processing method.
Background technique
In existing refrigeration system, the design of certain systems is very exquisite, need the ultra-thin tube of small diameter tube large capacity into Row is supported.
However in existing tubing manufacturing technology, the ultra-thin of manufacture small diameter tube large capacity is often carried out by the way of founding Wall pipe, but the manufacturing cost of founding is very high, energy consumption is also big, and certified product rate is not high.
Certain producers can be manufactured by the way of stretching pipe crimping, however plate both sides are frequently encountered in manufacturing process Dislocation is generated in curly course, the case where can not welding;Although energy consumption is little, the cost of material of manufacturing process compared with Greatly, and certified product rate is not also high.
Summary of the invention
The object of the present invention is to provide a kind of ultra-thin tube and its processing methods.The invention low production cost, production Tubing out meets the ultra-thin tube standard of small diameter tube large capacity, and cost of material is smaller, and certified product rate is high.
Technical solution of the present invention
A kind of ultra-thin tube, the wall thickness of the ultra-thin tube are 0.3-0.4mm.
A method of processing the ultra-thin tube, including step:
The first step, sheet shearing select the plate with a thickness of 0.3-0.4mm, calculate required plate according to the radius of required tubing It is spare to cut corresponding size plate for the width of material;
Second step, plate finishing, the plate that the first step is prepared, which is polished, to be modified, and removes flash removed;
Third step cleans plate, and the plate trimmed using ultrasonic water gun cleaning second step removes plate surface greasy dirt
Tubulose is made by veneer reeling machine in 4th step, roll bending molding, the plate that third step is trimmed;
5th step, welding, is welded into tubing for the 4th molding plate of step roll bending by HFI welding;
6th step, polishing welding seams remove the welding of the 5th step and complete the welding slag of tubing weld, and carry out sanding and polishing;
7th step, it is cooling, the 6th step is completed to the tubing of weld grinding, is cooled to room temperature by way of water cooling;
7th step, is completed cooling tubing by the 8th step, school circle, passes through school circular knitting machine school circle;
9th step, closing quotation, the tubing coil winding after high-ranking officers are round.
In the roll bending forming step, for veneer reeling machine by 12 groups of plain-barreled rolls, the plate that third step is trimmed is made required half The tubulose tubing of diameter.
For the veneer reeling machine by 12 groups of plain-barreled rolls, tubulose is made in the plate that third step is trimmed, the specific steps are:
A, the 1st, 2,3,4 group of plain-barreled roll upsweeps plate both sides, forms both sides arc and upwarps, the moulding of bottom level obtains Middleware a;
B, the 5th, 6,7,8 group of plain-barreled roll, which upwarps the both sides middleware a arc, continues to crimp, and forms semicircular moulding, obtains centre Part b;
C, the both sides middleware b arc is upwarped to continue to crimp and be closed up by the 9th, 10,11,12 group of plain-barreled roll, and the bottom of middleware b is rolled up Song forms circle, obtains the tubulose tubing of required radius.
In the step A, the 1st, 2 group of plain-barreled roll tilts on plate both sides upwards, forms that both sides are straight upwarps, bottom level Moulding;3rd, 4 group of plain-barreled roll upsweeps plate both sides, forms both sides arc and upwarps, the moulding of bottom level.
In the step B, the 5th, 6 group of plain-barreled roll crimps the bottom middleware a, forms both sides arc and upwarps, bottom arc Moulding;7th, 8 group of plain-barreled roll crimps the bottom middleware a, and the both sides middleware a are upsweeped, and forms semicircular moulding.
In the step C, the bottom middleware b is curled into the corresponding radian for meeting required radius by the 9th, 10 group of plain-barreled roll;The 11,12 groups of plain-barreled rolls upsweep the both sides middleware b, close up, and the tubulose tubing of required radius is made.
In the welding step, welding current 150-185A, speed of welding 2.3-2.7m/s.
In the polishing welding seams step, pass through the welding slag of planing tool polishing tubing weld.
In the school circle step, tubing after cooling is placed on the circular knitting machine of school along both direction counterclockwise rotation school circle.
Compared with prior art, the caliber low capacity of ultra-thin tube of the present invention is big, is particular enable to meet present refrigerant system design The requirement of middle delicate structure.
The processing method of ultra-thin tube of the present invention, plate, which is curled into round tube, by 12 groups of plain-barreled rolls can be avoided general stretching The plate both sides problem of misalignment generated during pipe crimping reduces the defect rate in production process, greatlys save production cost.
Deformation Law of 12 groups of plain-barreled rolls according to common plate in the processing method of ultra-thin tube of the present invention, can guarantee to roll up It will not be led to the problem of during bent and cause plate damage to cause defect rate high because of aging deformation;And 12 groups of plain-barreled rolls point It is particular enable to adapt to the production that wall thickness is 0.3-0.4mm tubing at the method that 3 steps crimp, yields reaches 99%.
Ultra-thin tube of the invention can be used for the evaporator, condenser, dew removing tube of the refrigeration systems such as refrigerator, refrigerator, whole Cost at least reduces by 1/5.
